JIECHENG Bi-Metal 4 inch Hole Saw with Arbor Mandrel for Cutting Wood,Cornhole Boards,Drywall,Plasterboard,Plywood,Steel,Aluminium,Brass,Copper,Zinc,Tin,102mm

I used this hole saw to install an electrical box in a plaster wall with 2 X 6 lumber behind. It bored through the plaster and wood with ease.

Wanted to make quick holes on the cealing for recessed lights. Cuts thru drywall like butter. Cant ask for more.

Perfect

Mine actually might be a touch smaller than 6 inches in diameter. If youre thinking of using this to cut recessed lighting can holes, like I did, you will have to ream them out after you cut, like I did.. Other makers make the saw slightly bigger than 6 inches. This one is small than 6 inches. Gave it 3 stars because it was not expensive.

If u plan on using this buy a different arbor. First use the arbor strips the threading. U need a arbor that has the 2 prongs poking into the saw. If u don’t, to much force and its game over. It’s almost worth just buying a saw that comes with the better arbor. Even going slow on drywall the thread will strip. I used mine for a hole for a dryer vent and I couldn’t even make it past the drywall.

I bought this hole saw to use for the construction of some washer boards. It cut all the holes very clean and worked great. I have not used it on metal yet but on the plywood it cut it like it was butter.

Poor quality

Works

Very satisfied. It cut through my metal garage door to install a vent. Took about a minute.

Used it to make a feral cat house. Cut right through a double sided cooler & didn’t leave rough sides to the cut.
